SPECIFICATION forming part of Letters Patent No. 767,142, dated August9, 1904.

Application iiled March 5, 1904. Serial No. 196,753. (No model.)

zen of the United States, residing at Philadel phia, county ofPhiladelphia, and State of Pennsylvania, have invented a certain new anduseful Improvement in Vending-Maehines, of which the following is aspecification.

My invention relates to a new and uset'ul improvement invending-machines, and has for its object to provide a vending-machinewhich is operated automatically and so constructed that upon the firstinsertion o't' the coin the spring-actuated delivery mechanism is set,and this delivery mechanism is then tripped by the weight of the coinfalling upon the treadle, the merchandise being locked in the holder atall times except when the lower package of merchandise is beingdischarged; and a further object of my invention is to provide thecoin-chute with a movable bottoni, whereby obstructions and illegalcoins are allowed to drop through the bottom of the chute.

With these ends in view this invention consists in the details ofconstruction and combination of elements hereinafter set forth and thenspecifically designated by the claims.

In order that those skilled in the art to which this inventionappertains may understand how to make and use the same, the constructionand operation will now be described in detail, referring to theaccompanying1 drawings, .forming a part of this specilication, in which"Figure I is a side elevation oi' my improved vending-machine mechanism,the parts being shown in the position assumed upon the `lirst insertionof the coin, the delivery mechanism being set; Fig. 2, asimilar viewtoFig. 1,shown ing the parts in position just before the coin falls uponthe tripping-lever; Fig.` 3, a similar view to Figs. l and 2, showingthe position of the parts after the delivery mechanism has been trippedandthe package of merchandise discharged; Fig. 1I, a section taken onthe lline 4 t oi' Fig. 3; Fig. 5, a section taken on the line 5 5 oi'Fig. 3.

A represents the casing of the machine, which may be oi any suitableshape or design and does not enter into my patent.

B is the delivery-chute for the merchandise.

G is a plate provided with an opening et just sul'licient size to allowthe insertion oi the proper coin therethrough. To the rear oit the plateis secured the coin-chute D, which consists ol two side walls, betweenwhich a `proper coin may pass, and a movable bottom E. Said bottom ispivoted at the points E to one of the sides o the chute, and the bottomis held normally up, so as to close the chute by means of a weight E,secured upon an extended arm E".

F is a bar adapted to slide longitudinallyof the coin-chute, this barbeing arranged at the upper end oi' the chute, a suilicient distancebeing left between the bar and the bottom of the chute to allow theproper-size coin to roll therethrough; but the forward end of said barlies rearward of the upper end of the slot through the plate C, so thatwhen thecoin is iirst inserted, as shown in Fig. 1, the bar will bepushed rearward a su'l'licient distance to allow the coin to dropdownward into the chute.

Gf` is the merchandiso-holder, in which the lpackages oi" merchandiseare arranged one on `top the other and fed downward by gravity.

The lower package of merchandise rests upona platform (if, and thei'ront and rear of the holder G is cut away from the platform upward adistance a little greater than the height of one package ot merchandise;but the lower package oit' merchandise is prevented from falling forwardby light springs G, which bear'against the forward tace ol said paekage,and this lower package of merchandise is prevented from being removedexcept at the proper time 'from the rear bym ans of the swinging door H,pivoted at its upper end to the merchandise-holder. This door isweighted so that it will normally always swing downward.

I is a shat't journaled in the standards which support themerchandise-holder, and upon this sha'lt is secured a plate J, and thisplate is normally heldin the position shown in ldig.` 3 by means of thespring J. Pivoted to the plate J at its forward end is a linger K, whichlinger has a plate K'. To the other end of the iinger upon the oppositeside of the pivotal point is secured one end oi a spring' l.

IOO

The otherend of the spring K2 is secured to the plate J. A stop isprovided upon the finger K to limit its movement in the direction inwhich the spring tends to throw the same. Thus when the parts are intheir normal position, as shown 4in Fig. 3, the iinger K will beunderneath the swinging door H, and said nger will be held in contactwith the lower edge of the door by means of-the spring K2, and the lugH', extending rearward from the door H, lies behind the plate K' uponthe linger, so that the door H is locked in its closed position, andtherefore the lower package of merchandise cannot be removed or jarredfrom its place in the holder. Secured upon the shaft I is a-segrnent L,to

which is secured eccentrically the lower end` of a link M, the linkbeing slotted at its lower end, a screw passing' through the slot in thesegment L. The upper end of the link M is pivoted to one end of a leverN, said lever be ing pivoted to the framework intermediate of its twoends at the point N'.

O is a link the outer end of which is pivoted at the same pointA wherethe link M and leverN are connected together. The other end of the linkO is provided with a slot O', through which passes a screw into theframe- Work.

Below the segment L is arranged a triplever P, pivoted intermediate ofits two ends to the framework, and upon the rearward end of said leveris provided a weight P', and the forward end of said lever is broadened,as indicated at P2, providing a plate upon which the coin is adapted tofall from the chute D. This triplever P is provided with a projectionP3, adapted to engage the notch L', formed in the segment L.

The forward end of the lever N lies, while in its normal position,directly back of the bar F, so that when said bar is pushed rearward bythe insertion of a coin, as shown in Fig. l, the lever N will be rockedupon its pivotal point, which will pull upward upon the link M, andthereby rock the segment L and revolve the shaft I. As soon as the notchL' of the segment L comes in register with the projection P3 upon thetrip-lever P the weight P' will then raise the forward end of the leverP and cause the projection P3 to engage the notch L', and thus hold theparts in the position shown in Figs. l and 2 against the action of thespring J'. By the revolving of the shaft I the plate J is rocked, andthis plate J, carrying the spring-finger K, will carry said fingerforward underneath the door H and platform G3 until it assumes theposition shown in Figs. 1 and 2, and the plate K' upon the finger K willbe caused to pass underneath the lug H' upon the door H, because as thefinger is dragged underneath the door it will be pressed downward, andtherefore the plate K' will pass underneath the projection H', and assoon as the nger has passed ver/,.142

clear of the platform G' it will spring into its normal positionrelative to the plate J, and when in this position a projection J 2 uponthe plate J will come behind the door H, as shown in Figs. l and 2, andtherefore again lock the door to prevent the accidental displacement ofthe lower package of merchandise.

The coin in passing from the chute D will drop upon the forward end ofthe trip-lever P, and the weight of the coin is sufcient to overbalancethe 'weight P', and therefore remove the projection P3 from the notchL', and therefore allow the spring J' to act to rock the plate J, theshaft I, and segment L. As soon as the plate J is returned to its normalposition by the spring J' the spring-finger K will will be carriedrearward with it and engage the forward face of the lower package ofmerchandise and remove the same from the rear of the holder, theplatform G' being divided, as shown in Fig. 4, to allow for the passageof the spring-linger in between, and as soon as the plate J commences tomove to its normal position the door H will be unlocked and it willswing upward to allow the passage of the package of merchandise, and assoon as said package has passed it will drop downward in the positionshown in Fig. 3 and again be automatically' locked.

The bar F is returned to its normal position by means of the spring F',and the lower surface of said bar is provided with teeth F2, adapted toengage a small gear-wheel Q, journaled in the sides of the chute D.Secured vupon the same shaft as the gear-wheel Q is a linger R, locatedin between the sides of the chute.

S is a magnet secured to the chute, and this magnet is adapted toattract and hold any iron or steel washers or disks placed in themachine, and when the neXt coin is placed in the machine the finger R inrevolving will disengage said iron washer or disk from the side ofthechute where it is held by the magnet and allow it to drop downwardthrough the bottom of the chute, the door at the bottom of the chutehaving been automatically opened in the manner I will now describe.

T is a bell-crank lever pivoted upon the outside of the chute, and onemember of this bell-crank lever rests upon the door E inside of thepivotal point of the door, so that when this member of the lever isdepressed the door will be swung open against the action of the weightE2. The member of the bell-crank lever which is in contact with the doorE is depressed on the iirst insertion of the coin, and the linger R inrevolving contacts the other member of the bell-crank lever, andtherefore will rock the same downward, opening the door. This will allowany mattei' previously located in the chute to escape, and on thecontinued movement of the bar F by means of the coin a wedge-shape lugupon the top of the bar F will come in con- IOO IIO
